RAILWAY-SWITCH APPARATUS.

Be it known that I, Jol-1N C. BRINK, a citizen of the United States, and residing at Middletown, -in the county of Orange and .5 State of.New York, have invented certain new and useful Improvements in 'RailwayvSwitch Apparatus, of which the following is a specication,A such as will enable those skilled in the art to which it appertains to make and use the same.

provide an improved apparatus of this class -which is simple in construction and positive in operation, and the construction of which vinvolves two separate lock members, one on veach side of the track and which are alter- 'nately operated 1n opening and elosingithe switch. and by means of which the .switch is positively locked both in the open and closed position, and with this and other objects in View the invention consists in an apparatus of the class specified, constructed and operating as hereinafterdescribed and claimed.

The invention is fully disclosed in the following specification, oi which the accompanying drawing forms a part, in which the Separate parts of my improvement are designated by suitable reference characters in each of the views, and in which -Fifrurel is a plan view of' my improved railway switch apparatus and showing the switch closed; Fig. 2 a sectional plan view but showing'the switch open; and, F ig. 3 a cross section on the line 3-3 of Fig. 2.

In the drawing forming part of this speciication, I have shown at a the main rails ot a railway track and at Z) a switch rail of a switch but the part b2 of one of the rails b, in the form of construction shown, also serves as one of the mainl rails, one rail being provided with a switch tongue 71"", and one rail e being provided with a switch tongue n?, said switch tongues being hinged to their respective rails at b4 and 'w3 as shown.

The switch tongues L and a2 are connected near their free ends by a transverse bar c which passes under the rails a and b-b2, this connection being made by means oit' plates c2 secured to the switch tongues and link members c3 pivotedto the bar o and to the plates c2. Y

At each side ot the track and on the vouter side of the rails thereof are placed parallel lock boxes cl which, in the construction Specification of Le'tterslatent.

shown are opened and secured tobase-boards or other supports c, and connected with the opposite ends ot' the bar c are lock links which are movable transversely through the boxes Il, and the lock links f are connected Vwith the ends of the bar c by bolts y having forked heads (/2 in which the ends of the bar c fit, and said forked heads (/2 are pivoted to the ends of said bar at 4l/i, and the bolts g,

--\inthe eonstruction shown, are screwed into This lnventlon relates to switch apparatus -for railways, and the object ther-ect 1s to the corsl)ondinghends of the lock links f.

The lock links are provided with central longitudinal slots f in the outer ends ot' which are-placed anti-friction rollers f, and the lock boxes (Z are provided in their opposite side walls with lgrooves Z2 in the same plane as the slots f2 in the lock links f.

Mounted in eorrespondingends ot the lock boxes Z are lock plates L, the outer corner portions ot the inner ends vof which are beveled inwardly, as clearly shown, und the lock plates t are movable longitudinally through the lock boxes d and through the locklinks Connected with the outer ends ot the lock plates z, are link bars 'i having yoke-shaped heads 2, one of which is connected, in each instance, with the correspondingr lock plate i, and the other end of the link bars 'i are vconnected with bell cranks j pivoted at f/" to the base-boards c and also to metal clips ',f secured to said base-boards, and extending transversely of the track, under the rails, and under the switch tongues, is a rod Z, the ends of which are pivoted to the bell. cranks at 7a2.

.In the construction shown an operating" lever m is pivoted to a support fm,2 at one sidepf the track as shown at mi* and aI rod n is connected with said lever at n and with one oi" the bell cranks y' at 71,3.

lV henthe switch is closed, as shown in Fig. l, one oi the lock plates L is in operation and the other is out of operation, but when the switch is open, as shown in Fig. 2, this position of the lock plates is reversed, and the lock plaie which is in operation when the switch is closed, as shown in Fig. 1, is out of operation when the switch is open shown in Fig. 2. It will also be observed that with the parts in the position shown in Fig. 1 in which the lck plate t at the right is in operation'and the switch is closed, if the lever be operated, the lock plate to the right will be drawn out of operation, and vthe lock plate 7L at the left will be thrown into operation, and in this operation of said again closed.

made wedge-shaped in The operation of the lock plates it and of the lock links f and the bar c is facilitated by the anti-friction rollers )"3 mounted in said lock links, and this operation depends on, or is the result of, the beveling of the outer corners of the inner end portions of said lock plates, whereby said lock plates are forni, oi` approximately so at their inner ends, and the positive lock of my improved apparatus depends upon the fact that the outer end portions of the lock plates i are rectangular in form and the opposite sides thereof parallel, this feature of the construction extending for approximately half of the length of said lock plates, and when either of the lock plates is in operation, neither the bar c nor the switch tongues can be moved except by the operation of the cross i'od it, as hereinbefore described.

It must also be understood that, in practice, the lockboxes d and the parts mounted therein and connected therewith may be, and are preferably inclosed, and this may also bc true of all the operative parts of my improved switch apparatus with the exception of the switch tongues Z13 and a2, and my invention is not limited to the use of the lever m for operating my improved switch apparatus, and said apparatus may be operated from a switch tower in the usual manner, and by any preferred means, and various changes in and modifications of the details of construction herein shown and described,

may be made, within the scope of the ap' pended claims, without departing rom the spirit of my invention. or sacrificing its advantages.

My invention is also not limited to the use of two switch tongues, nor to the arrang Lief-inea ment of and described, and the improvement which forms the basis of my invention may be applied to switches of any kind.

link members, and means for operating said lock plate members in opposite directions.v

2. In a railway switch apparatus, the combination with the usual switch tongues of a cross bar placed beneath the rails and said switch tongues and connected with said switch tongues, lock link members connected with the opposite ends of said bai', lock plates movable through said lock link mem)- bei-s, and means for operating said lock plate members alternately in opposite directions.

3. In a railway switch apparatus, a cross bar mounted beneath the rails and movable transversely thereof, lock links mounted in connection with the ends of said bar, locking devices movable transversely through said lock links, and means for alternately operating said locking devices in opposite direction and for locking said bar in different positions.

4. A railway switch apparatus involving the usual rails and switch tongues, a cross barwith which said switch tongues are con-- nected, lock members connected with the opposite ends of said 'cross bars, lock devices movable transversely of and in opermain and switch rails herein shown ative connection with said lock members,
